The system being described is the good ole days before the airlines and PAX demanded something more efficient. Now it is an line baggage system. Which while faster it is behind the scenes. To a certain degree it makes some sense. HOWEVER, after getting a tour of one inline system there is no reason why it needs to be behind a wall. In fact, I think it would be quite interesting from multiple points of views to have it fully visible to the general public. First, should inspections be visible to the public? Is there any difference between inspecting carry on baggage vs checked baggage? IMHO no, and yes. Next, I think from a how does an airport work it could be interesting to see a baggage system work. I mean image if there were windows all over an airport? Beside providing more light it would certainly provide more transparency. Imaging being in say ATL and watching your bags go zipping by while you walk down the concourse?

However, a bigger prevention would be simpler: the airlines are responsible for all baggage regardless of what is put in them.
